Photohelic 3000MR MRS系列ATEX IECEx认证的差压开关 显示仪说明书

Using solid state technology, the Series AT-3000MR/MRS ATEX/IECEx Approved Photohelic ® Switch/Gage combines the functions of a precise, highly repeatable differential pressure switch with a large easy-to-read analog pressure gage. Gage reading is unaffected by switch operation and will indicate accurately even if power is interrupted. The AT102-3000MR series employs versatile electromechanical relays with low amperage ratings-ideal for dry circuits. For applications requiring high cycle rates, choose AT102-3000MRS models with SPST (NO) solid state relays. Easy-to-adjust set point indicators are controlled by knobs located on the gage face (accessible opening case after de-energizing instrument). All models provide both low and high limit control. Compatible with air and other non-combustible, non-corrosive gases. Flameproof enclosures are available with a glass window which allows for viewing of set point needles and process pressure. Compatible with air and other non-combustible, non-corrosive gases.
BENEFITS/FEATURES
• Gage reading unaffected by switch operation and will continue to read pressure even during power loss
• Zero and range adjustments outside of gage means no disassembly in normal service
• Solid-state design allows for switching in high cycle rate applications without degradation
• Flameproof enclosure with optional glass window and aluminum housing protects the device in hazardous areas while giving local visibility to process pressure and set point status
APPLICATIONS
•
Hazardous area pressure measurement and switching • Pneumatic conveying • Air conditioning systems • Clean rooms
• Fume exhaust systems
